Discovery reports (1936) Discovery reports discoveryreports12inst Year: 1936 404 DISCOVERY REPORTS Length 50 mm. Pre-labral length 21 mm., width 28 mm. Post-labral length 29 mm., width 18 mm. Fore-body a little wider than long, wider than hind-body. Hind-body much wider than long, not concave behind. Abdomen large, fully segmented; somite 6 with a pair of large dorsal spines at posterior angles, and a pair of small spines dorsally on posterior margin. Telson elongated, nearly parallel-sided, with a transverse row of four large spines showing under the skin about the middle of it. Posterior margin with small points. Antennule with segment 2 of peduncle about half as long as segment 3 ; lengths of segments as 34: 11:21. Peduncle of antenna stout, without outer spines; flagellum slender, 50 mm. long. Fig. 16. Palinuurs sp., 50 mm. a. Dorsal view of head region. A i, antennule; A 2, antenna; C, cuticular elevation; E, eye-stalk. b. Maxillule. c. Telson and uropods. Maxillule with only a vestige of the palp (Fig. i6b). Maxilla with large exopod fringed with setae. Maxillipede i large, with epipod. Maxillipedes 2 and 3 with long setose exopods. Maxillipede 3 and legs 1-4 with very small coxal spines. Leg 5 of five seg- ments, without exopod. All gills present. Pleopods large, with appendix interna free. Uropods large, with spine on outer margin of both branches, a basal muscular part distinct from a distal part which shows internal striation (Fig. 16 c). There can be very little doubt that this Phyllosoma belongs to a species of Palinurus, although it differs from P. vulgaris and P. gilchristi in not having a definite palp on the maxillule. On the other hand, it agrees with them in the proportional length of the segments of the antennular peduncle, which seems to be a very good generic character. The only species of the genus from this region is P. lo?igimamis var. maiiritianus, Miers. The great size of the Phyllosoma as compared with that of P. vulgaris is remarkabl
